Markets

A market is a system/infrastructure which people use to engage in economic exchange. In a narrower sense, a marketplace is a website or a software application, which connects buyers and sellers, allows them to list their own items and processes the transactions between them. There are many examples of successful marketplaces of all kinds, including giant companies that serve everyone, such as eBay or Shopify, and smaller companies which focus on some specific aspect, such as the Bitcoin-only OpenBazaar.
